COTTON-STALK PULLER.

SPECIFICATION forming part of Letters Patent `No. 446,276, dated February 10, 1891.

Application filed September 2,1890. Serial No. 363,797. (No model.)

To all whom it may concern:

Be it known that I, LEwIs L. WOMACK, of Zephyr, in the county of Brown and State of Texas, have invented a new and useful Improvement in Cotton-Stalk Pullers, of which the following is a specification.

My invention is an improved machine for pulling cotton-stalks from the ground, and has for an object. to provide a machine simple of construction, easy of operation, and efficient in use.

The invention consists in certain novel constructions and combinations of parts, as will be hereinafter described, and pointed out in the claims.

In the drawings, Figure lis atop plan View, Fig. 2 is a sectional side view, and Fig. S is a sectional front elevation, of my machine; and Fig. 4 is a detail sectional view of thepulling-wheel and the constructions for supporting the same.

The axle A is journaled in the main frame B and has one or both wheels C secured to it, so that the axle will be turned as the implement is moved along the ground. Below the axle A the main frame is provided with abar D, extended in line with the axle and provided centrally with a bearing CZ for the upper end of the shaft of the pulling-wheel. By preference this bar D is fixed at its ends to the under sides of the boxes b, in whichthe shaft A journals. A hanging frame E is also supported on the main frame and consists of the base-plate F and the rods G, which extend from the corners of the base-plate F to 'the corners of the main frame and support the plate G rigidlyin position below the axle.

In the plate F is formed a bearing f, arranged vertically below the bearing d in bar D. The arrangement of the supporting-rods G is such that a wide space is provided within the frame E immediat-ely below the bar D,in which the large horizontal gear presently de- `scribed. may operate.

The shaft H of the pulling-wheel I has a shoulder h, which rests on the plate F, a round portion .I below such shoulder, which journals in bearing f, and a squared portion K below part J. This portion K receives the wheel I and has a series of perforations l.; for a pin L, which is arranged below the said wheel I and maybe adjusted in to one or the other opening 7c to hold the wheel at different heights. Above the shoulder h the shaft II is squared to-receive the large gear-wheel. M, which is arranged to operate immediately below the bar D. At its upper end the shaft II is rounded and fits and turns in the bearing d of bar D.

The wheel M is meshed by a pinion m on the axle A, said pinion being arranged at the left side of the wheel M, so that as the implement moves forward the wheel M, its shaft, and the attached pulling-wheel will be turned from right to left, the direction of motion of thepulling-wheel being relative to the inclination of the pulling-pins, as hereinafter dcscribed.

The pulling-wheel I is formed with a dish or concave rounding up toward its center, where it is secured on the shaft II in the manner before described. I make this wheel with spokes O and a rim I), the latter being mortised out at p to form seats for the .pins or teeth Q, which tit at their inner ends in the said seats and are secured by bolts, as shown. The seats p are formed and arranged to secure the pins or teeth approximately at a tangent to the frame or main portion of the wheel, so that the teeth will project at a tangent and operate to receive the stalks as the machine moves along the row. The spaces between the teeth and the rim of the Wheel receive t-he stalks and the said spaces open rearward ly with respect to the direction in which the wheel is turned. v

As shown by the arrow, the pulling-wheel is turned in a direction to cause its side engaging the cotton-stalks to move rearwardly or in adirection opposite to that in which the machine is advancing. The wheel operates to pull the stalks by reason ofthe difference between the speed at which the wheel is turned and that at which it is moved over the ground, the wheel being moved forward at a faster speed than it turns back, so that as the stalks are caught by the vteeth they will be pulled forward out of the ground, and as the wheel turns back they will be carried back to a point in rearof the machine, where they IOO will be discharged, the discharging of the stalks being made certain by means of a dischargingbar R, secured at one end to the hanging frame E and arranged at its other end to vproject over the wheel above the teeth and to foroe the stalks out of the spaeebetween the pin and Wheel-rim, and so clear the Wheel. 'The tongue is secured to the main frame about in line With the rearwardlymoving side of the pulling-wheel, so as to place the draft in the direction of greatest strain, and the doubletree is placed below the tongue, in order to exert a lifting tendency on lthe main frame and the parts supported below the same.

Having thus described my invention, what I` claim as new isl. In a stalk-puller, a pulling-Wheel having its rim formed with seats p for the inner ends of the pins Q, the pins Q, fitted at theirinner f en ds in said seats and proj eating at their outer ends at :atan gent,and the-fastenings by which to secure the pins to the Wheel, substantially as and for the purposes set forth.

2. In a stalk-puller, the combination of the axleand main frame, the pulling-Wheel having its rim provided with tangentially-projeeted Wheel N, dished upward toward the center,y

fitted at the center on the shaft H, and provided at its rim with pins Q., and the pins L, by which the Wheel N may be secured at different heights, all substantially as and for the purposes set forth.

4. In a machine substantially as described,

a pulling-.Wheel provided at its 'rim with tan@ gentially-prfojected pulling-pins, 'substantialvly as set forth.
